MACHINE FOR.BUNDLING SCRAP.

Patented Apr. 23,1912,

To all whom it may concern Be it known that 1, CHARLES W. BEN- ofPittsburgh, Allegheny .county, Pennsylvania, have invented a new anduseful Machine for Bundling Scrap, of which the following is a' full,clear, and exact description, reference being had to the acforming partof this specification, in which- Figure 1 is a front elevation of oneform Fig. 2 is a section on the'line II-II of Fig. 1; Fig. 3 is a topplan' view; Fig. 4 is a detail section taken on the dine IVIV of Fig. 2and showin the wire-twisting or tie devices; and.- ig. 5 is ar detailview of a porthis character tion of the gearing.

My invention has relation to machines for bundling metal scrap, and isdesi ed to provide a sim le and eiiicient mac ine of by means of which"metal scrap may be rapidly bundled and the bum dles pro erly tied orsecured by the operation of t emachine.

' In these drawings, the numeral 2 designates the driving shaft of themachine,

{carrying the driving pulleys 3, and also a spur toothed pinion a, whichengages the 1 large spur gearwheel 5 on the parallelshaft 6. The wheel 5isrotatably mounted on the shaft -6, and is designed to be, connectedthereto through the medium of a clutch 7 which is arranged to slide intoand out of engagement with a clutch hub 8 of the wheel 85*5. The clutchmembers are arranged to be levers 16 thrown into clutching engagement bythe action of a spring 9, andto be thrown out often agement by means ofa shifting rod '10, w ich cooperates with the cam surface 11 "ontheclutch 7. The shifting member v3.0 is connected to the foot lever 12.

13 designates a pocket or receptacle formed at the upperfront portion ofthe machine, the scrap to be bundled is to be placed. The rear wall ofthis pocket is formed by the overhung arms is, and its "front wall isformed by the series of fingers 15, which form extensions of the seriesof; "igidly secured to a rock shaft-17,

"one of said levers being counterweighted at 18, and another of saidlevers having a downwardly extending arm '19 --pro.lded with annntitriction roller ramgefi=to engage a cam '21 on the shaft 5.

"20 which is aremployed s- Each I also preferably, although notnecessarily,

provide the pocket with onchrmoreguide or guard fingers 22 for thepurpose ofrpre venting an undue amount of scrap from being placed in thepocket or receptacle at one time. The arms 14 and the fingers 15 haveconcave inner surfaces, for the purpose of shaping the scrap into abundle of approxi matel'y cylindrical form. I

23 designates one of the tie wires, a series of these wires being fedinto the machine throu h a series of adjustable tension and straigtening rollers 24 and between the upper and lower feed rollers 25, oneof said rollers preferably being adjustably held in position by means ofset screws 26. 'The tie wires then pass thr oughlthe rotary twistingheadsn27. In the machine; shown in the drawings, three ofithese twistingheads are provided, as shown in Fig. 4, but it will be obvious that anysuitable number may be of the twisting heads is driving pinion 28, thepinprovided with a ion of the middle head being driven by a spur gearwheel 29 (see Fig. 2), on a shaft 30. The Shaft SO carries a bevel gear31,

which is driven by a bevel gear wheel 32 on an oblique shaft 33, whoselower end has a bevel pinion '34, which meshes with a mutilated orsegmental bevel gear 35 on the shaft 6 (see Fig. The pinions 28 on theside twisting heads-are driven by the inter mediate idle gears 37, asshown in dotted lines in Fig. l.

36 is a mutilated or segmental spur gear on the shaft 6, which isarranged to drive a pinion 39 on a shaft 40. On the shaft 40 is adriving wheel 41, which is connected by a chain or other belt 42 withthe shaft of one of the feed rolls 25.

The tie wires 23 pass obliquely through. the front ends of the twistingheads, and thence downwardly through suitable guides 43 underneath thepocket or receptacle 1.3,as clearly shown in Fig. 2.. On the forward end(it each twisting head is a disk or plate 44 having a peripheral notch4-5 into which the free end portion of the tie wire is adaptcd to bebrought after it has been carried ltlt . arms 14-, thereby compressingthe scrap into ferred to.

ing up the slack the feed-1n rollers to cause suiiicient lengths eratorremoves his'foot from the ,lever or .eiiicient means for tacle 13. Thisshaft is provided with a spur regular pieces of scrap may be readilycomwheel 48, whose teeth are engaged by a toothed rack 49, connected toa bell crank lever 50, having an antifriction roller 51, which is inengagement with the cam 52 on the shaft 53 driven from the shaft 6 by achain or belt 54, or other suitable means.

55 designates a tension spring connected to one arm of the bell crank 50for the purpose of holding the antifriction roller 51 in engagement withthe cam;

56 designates the cutoff slides, which are mounted to reciprocatevertically in suit-able guides 57 (see Fig. 2), and each of whichcarries a cutter 58 at its upper end, which is for the purpose ofcutting oil the tie wire after each bundle has been tied. Each cutoilslide is provided with an antifriction roller 59, at its lower end,which contacts with a cam 60 on the shaft 53 before re of the fingers15, and the formed bundles tied mechanically without the necessity formanual operations.

Various changes may be made in the departs. Thus, the arrangement of thedriving gear for the several mechanisms may be widely changed; differentforms of twisting heads may be employed;

ways, and numerous changes may be made within the scope of the claims.

I claim zpocket or receptacle for the scrap to be bundled, mechanism forcompressing or shaping the scrap into bundles, feed devices for feedingthe forward end of a coil of tie wire around a formed bundle in saidpocket, means for tying the bundle encircling wire into a loop and meansfor sevgring the formed loop from the coil; substantially as described.

2. In a machine for bundling scrap, a pocket or receptacle for the scrapto be bundled, members for compressing the 61 designates an adjustableidler for tak-" of the belt 42.

The operation is as follows :-The scrap to be bundled is to' be placedin the pocket or receptacle 13; and when a sufiicient quantity to form abundle has been placed there in, the operator depresses the foot leveror treadle 12; ereby throwing the clutch 7 into driving engagement withthe hub of the gear wheel 5. This causes the shaft 6 to commence torotate and the cam 21 to act upon the antifriction roller 20 to actuatethe series of levers 16 to cause their fingers 15 to move rcarwardly orinwardly toward the av compact approximately cylindrical bundle. At thistime the cam 52 operates the bell crank lever 50 to actuate the rack'4-9 and thereby rotate the shafts? an dswing the fingers 4-6 upwardlyand overtp ctirry the tie wires 23 around and over the formed bunsdepositing the free end coil; substantially as described.

At this time the mutilatedbevel gear 35 comes in engagement with the bevel ear wheel 34 androtates the shaft 33, thereby rotating the series of twisting heads andforming the ties. The cams 60 now operate the slides 56, and thereby thecutters 58;[0 sever the tie wires 23 from the bundle. The toothedsegment 38 of the w eel 36 then commences to rotate the pinion 39 toactuate dled, a ser es of levers having fingers extending at the rear ofthe pocket or receptacle means for actuating said levers, tie Wirefeedirgmechanism, a movable finger or arm forcarrying the tie wirearound the formed hundle, and twisting devices for the tie wire;substanlly as described.
